Kind Code:
B2
Abstract:
An endoscope system includes an endoscope and a processor. The endoscope includes: an actuator including a coil configured to cause a movable lens and a magnet to move by application of a drive signal; a position sensor configured to output a position detection signal showing a position of the movable lens according to a magnetic flux of the magnet; and an endoscope memory storing correction information for correcting crosstalk onto the position detection signal by the magnetic flux of the coil. The processor includes a drive controller configured to correct the position detection signal based on the drive signal and the correction information and output the drive signal based on a target position and the corrected position detection signal, to the actuator.
